20220371232 · 2022-11-24 ·

A method of manufacturing a microfluidic architecture having at least one channel disposed therein. Steps can include pouring an uncured polymeric material into a mould to produce a first layer; at least partially curing the first layer; and forming the at least one channel by disposing a support material on the first layer; pouring an uncured polymeric material onto the first layer to form a second layer to thereby encapsulate the support material; and at least partially curing the second layer such that the first layer and second layer together form the microfluidic architecture; wherein the support material undergoes a phase change during the process of forming the at least one channel. The phase change of the support material enables the material to be more easily disposed and/or removed after formation of the channel.

MICRO VIBRATION BODY HAVING THREE-DIMENSIONAL CURVED SURFACE SHAPE AND METHOD FOR MANUFACTURING THE SAME

In a method for manufacturing a micro vibration body having a three-dimensional curved surface, a mold defining a recess part is prepared, and a plate-shaped reflow material is arranged on the mold so as to cover the recess part. Pressure of a space defined by the recess part covered with the reflow material is reduced, and the reflow material is deformed by heating from an upper surface side opposite to a lower surface facing the recess part and by means of the pressure reduced. When the reflow material is deformed, a part of the mold is heated and / or cooled. As another example, when the reflow material is deformed, a mold having a different heat capacity portion is used to generate a temperature gradient in the mold.
